United States Patent LIVESTOCK OILER Kyle I. Delp, Norfolk, Nebr.

Application December 19, 1957, Serial No. 703,924

10 Claims. 01. 119-157 This invention relates to a livestock oiler and more particularly to an oiler for hogs.

An object of the invention is to provide a practical hog oiler which is simple in design, easy to service and install, and which operates automatically upon the rubbing of hogs by discharging a proper quantity of oil onto the oil conducting and scratching outer surface of a post-like oiler.

My invention is exceedingly simple in mechanical detail having no pumps, valves, etc. or parts generally considered as such to become clogged and unsatisfactorily operative. My hog oiler has the oil distributed to the outer covering by relying on the flow due to gravity. There are orifices in the chamber that stores the oil and these are opened automatically when the hogs rub up against the scratching surface of the covering so that oil is discharged as it is used and needed.

Other objects and features of importance will become apparent in following the description of the illustrated form of the invention.

Figure 1 is a perspective view of a hog oiler which exemplifies how the invention may be embodied in one practical oiler.

Figure 2 is a sectional view on enlarged scale and taken on the line 2-2 of Figure 1.

Figure 3 is an enlarged transverse sectional view taken on the line 33 of Figure 2.

Figure 4 is a transverse sectional view taken on the line 44 of Figure 2.

Figure 5 is an enlarged fragmentary sectional view showing the oiler as it appears when moved to a position at which oil is discharged to the outer covering of the oiler.

Figure 6 is an exploded perspective view of a part of the oiler.

In the accompanying drawings there is a hog oiler 10 which is constructed in accordance with the invention. The oiler has a platform 12 which is optional. An area 14 of the platform is enclosed by fence 16 in the center of which there is a base 18 bolted or otherwise held in place. A column 20 is welded or otherwise rigidly secured to base 18 and has a piston 22 at the upper extremity thereof. The piston head 24 is made of a leather or like material with washers 26 and 28 on opposite sides thereof and having a skirt 30. Nuts or other fasteners are used to hold the piston assembled on column 20.

A cylinder 32 is mounted for reciprocation on column 20 with the skirt of the piston sliding against the inner surface of the cylinder. The lower wall 34 of the cy1inder has a guide aperture 36 in its center through which the column 20 is passed. Stop 38 is attached to the column and abuts the inner surface of wall 34 to limit the upward movement of the cylinder. Guide 40 is attached to the cylinder 32 near its upper extremity and it has a downwardly sloped upper surface 42 which tends to guide oil which accumulates beneath the piston, toward the walls of the cylinder 32. A plurality of oil discharge apertures 44 are in the side wall of the cylinder 32 and are located above and at the edge of the sloped upper surface 42 of guide 40. The main discharge openings or orifices 46 are formed in a group above apertures 44 and these are registered with the oil 48 in oil chamber 50 when the cylinder is lifted. The discharge orifices 46 move past the piston 24 as the cylinder moves upward and become registered with the oil 48 enabling it to flow to the outer surface of the cylinder 32.

Chamber 50 is filled by lifting the loosely fitting closure 52 and pouring oil into the open upper extremity of the cylinder which constitutes chamber 50. Closure 52 fits sufliciently loose so that no appreciable vacuum will be formed above the oil level. Accordingly, there will be no serious retarding of the flow of oil through orifices 46 when cylinder 32 is lifted.

The cylinder 32 is lifted by the rubbing action of the hogs on the scratching surface 56 of a cylinder covering. The scratching surface is formed by a wire mesh screen 57 whose confronting edges have flanges 58 and 60 (Figures 3 and 6) that engage and lock, holding the screen 57 in cylindrical form on the pliers or layers of burlap 62 that are on the outside surface of cylinder 32. The burlap functions as a wick by which to conduct the oil and the wire mesh screen not only protects the burlap but also provides a scratching surface for the hogs. When applying the burlap and the wire mesh to the cylinder it is recommended that a number of ties 64 be placed on the outside surface of the wire mesh to help hold it fastened firmly in place and prevent the hogs from pulling it loose.

The operation has been partially described previously. The hogs rub onto the outer surface of the post-like hog oiler not only scratching but also receiving oil from the cover on cylinder 32. At the same time their movements will cause the cylinder to ride up and expose the contents of the chamber 50 to the layers of burlap 62 or like material, such as cloth of other types, through orifices 46. When the hogs move from contact with the scratch surface, the cylinder 32 is gravity lowered. This closes registry between the oil 48 and the covering on cylinder 32.

An important feature of the invention is bafiie at the top part of screen 57. The upper part of screen 57 can be rolled over the annular baffle 75 to hold it in place. The proper position for the bafile is in alignment with orifices 46 (Figure 2) to prevent the oil in chamber 50 from squirting completely through the covering on cylinder 32.

It is understood that various changes may be made without departing from the claimed invention.

What is claimed as new is as follows:

1. A hog oiler comprising a base, an upstanding column attached to said base at one end and having a fixedly mounted piston at its opposite end, a cylinder mounted on said column and slidable over said piston, said cylinder having at least one discharge orifice located below said piston when said cylinder is in its lowered position, the volume enclosed by said cylinder above said piston constituting an oil storage chamber, a covering on said cylinder and against which the hogs are adapted to brush and thereby elevate said cylinder to bring said orifice in registry with said chamber and thereby discharge oil from the chamber onto the covering which has a portion in oil receiving communication with said orifice.

2. The oiler of claim 1 wherein said covering includes at least one ply of oil saturable material, and a screen mesh over said ply.

3. A hog oiler comprising a base, an upstanding column attached to said base at one end and having a fixedly mounted piston at its opposite end, a cylinder mounted on said column and slidable over said piston, said cylinder having at least one discharge orifice located below said piston when said cylinder is in its lowered 3 position, the volume enclosed by said cylinder above said piston constituting an oil storage chamber, a covering on said cylinder and against Which the hogs are adapted to brush and thereby elevate saidcylinder to-bring said orifice in registry with'said chamber and thereby discharge oil from the chamber onto the covering which has a portion in .oil receivingcom-munication with said orifice, a guide secured to said cylinder and having an opening through which said column is passed, the upper surface of said guide sloping downwardly and outwardly toward the walls of said cylinder, and said cylinder having at least one aperture at the edge of said guide through which oil which accumulates on the sloping surface of said guide may .pass and be received by said covering.
